> Jitrino.OPT crashes instead of throwing NoClassDefFoundError if call a method with array of objects of non-existing class as returning type
> Please, consider the following code:
> -------------------------------------------------------
> public class Reproduce {   
>     
>     public static void main(String [] args) {
>         new TClass().test1();
>     }

>    
> 	 void test1() {
> 		 RemoveMe[] arr = test();
> 	     RemoveMe element = arr[3];
> 	 }
> 	 RemoveMe[] test() {
> 		 return new RemoveMe[10];
> 	 }
> }
> class RemoveMe {}
> ---------------------------------------------------------------
> Steps to reproduce: 
> 1) compile Reproduce class
> 2) remove RemoveMe.class
> 3) run Reproduce.class
